How to write a thesis outline, with chapter word counts
By Mubarak MutesasiraUpdated 9 min read
Short answer:
A thesis outline is a chapter-by-chapter plan of your thesis: each chapter's purpose in one sentence, its main sections, and a word budget that adds up to your university's limit. Most empirical theses follow introduction, literature review, methodology, results, discussion and conclusion. Write the outline early, from your research question, and revise it as the work develops.
This guide is for undergraduate, master's and PhD students planning a thesis or dissertation. It is part of our planning series; the hub is how to write a research question.
What is a thesis outline?
A thesis outline is a structured plan that lists the chapters of a thesis, the purpose and main sections of each, and how many words each will take. It is a working document, not a table of contents: it shows the argument and the budget, and it changes as you learn more.
A good outline does three jobs. It lets your supervisor see the argument before you write it. It turns a word limit into chapter targets you can plan your time around. And it shows gaps early, such as a research question that no chapter answers.
What are the 5 chapters of a thesis?
The traditional thesis chapter structure has five chapters: introduction, literature review, methodology, results, and discussion with conclusions. Many universities split discussion and conclusion, giving six.
| Chapter | Purpose | Main sections |
|---|---|---|
| 1. Introduction | Why this study matters and what it asks | Background, problem, aim, research questions, significance, structure of the thesis |
| 2. Literature review | What is known and where the gap is | Themes, critique, the gap, theoretical or conceptual framework |
| 3. Methodology | How you answered the questions and why | Approach, design, sample, instruments, procedure, analysis, ethics, limits |
| 4. Results or findings | What you found | Results by question or hypothesis, or findings by theme |
| 5. Discussion and conclusion | What it means | Findings against the literature, implications, limitations, future research, conclusion |
Front matter (title page, abstract, acknowledgments, contents) and back matter (references, appendices) sit around these. Check whether they count toward your limit: rules differ between universities and even between departments.
Thesis chapter structures by field
Not every thesis follows the five-chapter model. Paltridge's study of thesis guides and real theses describes several common shapes [1]. Choose the one your field and department use.
| Structure | Common in | Chapters |
|---|---|---|
| Traditional, single study | Social sciences, education, nursing, business, many master's degrees | The five chapters above |
| Traditional, several studies | Psychology, life sciences, engineering PhDs | Introduction, literature review, general methods, one chapter per study (each with its own methods, results and discussion), general discussion |
| Topic-based or argument-led | History, philosophy, literature, law, parts of the humanities | Introduction, then chapters each named for a sub-topic or argument, then conclusion |
| Thesis by publication | Sciences and some social sciences | Introduction and literature review, three to five papers (published, submitted or in manuscript form), a linking discussion |
A thesis by publication follows the rules of your university on how many papers, what status they need, and how co-authored work is declared. Read those rules before you plan.
How many words per chapter in a thesis?
Your university sets the total word limit, and your field and supervisor shape how it splits. Limits vary widely. At the University of Cambridge, for example, the History and Philosophy of Science PhD has an 80,000-word limit including footnotes [2], while the Engineering PhD has a 65,000-word limit with different rules on what counts [3]. Check your own handbook for the limit and for what is counted.
The ranges below are typical for a traditional empirical thesis. They are starting points to agree with your supervisor, not rules.
| Chapter | Typical share | 10,000 words (undergraduate) | 15,000 words (master's) | 80,000 words (PhD) |
|---|---|---|---|---|
| Introduction | 5–10% | 500–1,000 | 750–1,500 | 4,000–8,000 |
| Literature review | 20–30% | 2,000–3,000 | 3,000–4,500 | 16,000–24,000 |
| Methodology | 10–20% | 1,000–2,000 | 1,500–3,000 | 8,000–16,000 |
| Results or findings | 20–30% | 2,000–3,000 | 3,000–4,500 | 16,000–24,000 |
| Discussion and conclusion | 15–25% | 1,500–2,500 | 2,250–3,750 | 12,000–20,000 |
The ranges overlap on purpose: a qualitative thesis often has a longer findings chapter; a thesis built on a new method may need a longer methodology; a humanities thesis has no methods chapter at all. Pick one number per chapter so the budget adds up exactly.
Thesis outline examples
These examples were written for this guide. Each budget adds up to the total.
Example 1: master's dissertation, 15,000 words

| 1. Introduction | 8,000 | 10% |
| 2. Literature review and theoretical framework | 16,000 | 20% |
| 3. General methodology | 10,000 | 12.5% |
| 4. Study 1: survey of 1,200 nurses | 12,000 | 15% |
| 5. Study 2: interviews with 24 ward managers | 12,000 | 15% |
| 6. Study 3: intervention pilot on four wards | 12,000 | 15% |
| 7. General discussion and conclusion | 10,000 | 12.5% |
| Total | 80,000 | 100% |
Example 3: humanities, argument-led, 80,000 words
Introduction (8,000); four chapters of 16,000 each, named for their arguments, such as "Print and the parish: reading networks in 1790s Lancashire" (64,000); conclusion (8,000). Total 80,000. The literature and method are discussed in the introduction and within each chapter, not in separate chapters.
How to write a thesis outline before your literature review is finished
You do not need to have finished reading to outline. Use this procedure:
- Write the research question and sub-questions at the top of the page. If they are not settled, settle them first with our research question guide.
- Choose the structure your department uses: traditional, several studies, topic-based or by publication.
- Map each sub-question to a chapter or section where it will be answered. A question with no home is a warning sign.
- Write one sentence per chapter saying what it does for the argument.
- Split the literature review into provisional themes from your proposal and early reading. Mark them "provisional".
- Set the word budget from the ranges above so it adds up to your limit.
- Turn the budget into a timeline. Divide your months by the chapters, leaving at least a month at the end for revision.
- Review it with your supervisor, then revise the outline each time a chapter is drafted.
Keep the outline in the same document as your thesis draft, so headings move with it.
Common mistakes in a dissertation outline
- Copying a table of contents. Headings with no purpose sentence do not show the argument.
- A budget that does not add up, or that ignores what your university counts (footnotes, tables, appendices).
- A literature review that takes half the thesis. Long reviews usually squeeze the discussion, which is where examiners look for your contribution.
- No place for the framework. Decide where your theoretical or conceptual framework sits.
- A methodology that does not match the results. Every analysis in the methodology chapter should produce something in the results.
Build a thesis outline in AI for Research
The Thesis outline module in the Thesis Suite drafts an outline from your topic (3 credits). You choose the degree, the total length (10,000, 20,000, 40,000, 80,000 or 100,000 words) and the structure: traditional, thesis by publication, or humanities with argument-led chapters. It returns a working title, the research question and objectives, each chapter with its purpose and sections, citing sources where a chapter builds on them, and a word budget table whose numbers add up to the total you chose. Open it in the editor and edit it there.
- Plan one chapter in detail with the free thesis chapter planner: sections, what each must cover, papers to start from, and questions examiners may ask. Signed out, it allows 3 runs a day.
- Turn the budget into dates with the Timeline module (3 credits): phases, milestones and risks over the months you have.
- Share the outline in a Project with your supervisor as "can comment".
- Export to Word or LaTeX when you are ready. See Word and LaTeX export.
The free plan has 45 credits a month; see pricing. The module does not know your university's word limit rules or what counts toward them: check the handbook and adjust the budget.
FAQ
What are the 5 chapters of a thesis?
The traditional five-chapter thesis has an introduction, a literature review, a methodology, results (or findings), and a discussion with conclusions. Many universities split the last one into a separate discussion and conclusion chapter, giving six. This structure suits a single empirical study. Theses by publication, humanities theses and multi-study science theses use different structures, so check what your department expects.
How long is each chapter of a thesis?
It depends on the total length and your field, and your university sets the overall limit. As a typical pattern in a traditional empirical thesis, the introduction takes about 10%, the literature review 20 to 30%, the methodology 10 to 20%, the results 20 to 30% and the discussion and conclusion 15 to 25%. Treat these as starting ranges to adjust with your supervisor, not rules.
How long should a thesis outline be?
A working outline is usually one to three pages: a working title, the research question, each chapter with its purpose in one sentence, its main sections as bullets, and a word budget. A PhD outline may run longer because it lists more sections. If your outline grows to many pages of prose, you have started drafting, which is fine, but keep a short version for meetings with your supervisor.
Can I write a thesis outline before finishing my literature review?
Yes, and you should. Write a provisional outline from your research question and proposal, with the literature review split into the themes you expect. Mark those themes as provisional and revise them as your reading changes the picture. An early outline lets you set a word budget and a timeline and shows your supervisor where the argument is heading.
Can AI write my thesis outline?
AI can draft a first outline from your topic, degree and target length, including a word budget, which is useful for structuring your first meeting with your supervisor. It cannot know your department's rules, your data or what your examiners will expect. Use the draft as a starting point, check it against your handbook, and rewrite the chapter purposes in your own words.
